The team brings an Appalachian-style cabin all the way to western Colorado.

In the shadow of the New River Gorge Bridge, the Barnwood Builders work with three centuries of materials and techniques in one project. Using custom 21st century steel brackets and hand-hewn 19th century beams, they create a one-of-a-kind pavilion for the Wild Rock Community Center.

The guys take down a massive double-pen barn in southern Indiana. While they work to save every log and barn board, Mark visits an incredible lodge built from a different barn they took down in nearby St. Meinrad.
